GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 408,980, dated August13, 1889. Application filed January 28, 1889- Serial No. 297,855. (Nomodel.)

To all whom it may concern.-

Be it known that we, JONATHAN J OHN- SON and EDMUND I-I. PAOKER,citizens of the United States, residing at Lowell, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Gas-Heaters; and we do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe sam e, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to an improvement in that class of heaters orradiators in which gas is used for fuel, the 'object being to soconstruct the radiators that the number of parts shall be few andreadily connected, and by using two sets or rows of radiator-pipes, oneof which receives the burners and has an upward current through them,and then returning the products of combustion downward through the otherset of radiator-pipes, ex tract all the available heat produced bythecombustion of fuel.

A further object is to so construct the gasburner that the gas shall bethoroughly mixed with air before burning.

To effect these objects we construct a base with two chambers, one ofwhich receives the gas pipe and burners, and into which chamber is alsosecured a chamber, which forms a return for the products of combustionpassing up through the first row of tubes to a corresponding row placedparallel with the first, down through which they pass to the otherchamber in the base, and from which chamber they are carried by asuitable flue to a chimney or other proper place of exit. The burnersare placed in line beneath the vertical tube and are each provided witha branch pipe, through which the atmospheric air mixed with the gasbefore burning passes.

In the accompanying drawings, which illustrate this invention, Figure 1is a perspective View of the heater complete. Fig. 2 is a verticalsection through the same on the line 0300 of Fig. 1, showing thearrangement of the gassupply pipes and burner, radiating-pipes, and

the chambers which they connect. Fig. 3 is a perspective View of thegas-pipe and burners removed from the heater. Fig. 4 is aview, partly insection, of a pipe with one of the burners upon an enlarged scale tomore fully illustrate its construction; and Fig. 5 shows a modificationof the deflector.

In these several figures, A represents the chambered base, preferably ofcast-iron, and provided with suitable legs A to support it a properdistance from the floor. One chamber of this base, as B, is open at thebottom and is intended for the reception of the supply-pipe and burners.The other chamber B is closed at the bottom and provided with anexit-pipe a, through which the waste products of combustion escape.Secured in the top of this base A and opening into the chambers B and Bare two rows of vertical tubes or radiating-pipes C O. The tops of theserows of pipes enter into and are connected by a chamber D, which mayalso be of cast metal and provided with-a removable cover D, by theremoval of which access is gained to the upper ends of theradiating-pipes. The gas-supply pipe E, which supplies the burners, iscarried in suitable bearings at each end of the base A, and extendsbelow the chamber B from one end of the base to the other. Screwed intothe upper side of this pipe E is a series of burners bone for eachradiating pipe or tube in the row above it. A short pipe I) is screwedinto the pipe I) diagonally or is formed integral therewith, and admitsair to the gas that flows through the burners, the size of the openingin the pipes Z) and I) being adjusted to allow the mixture to issue atthe top in such a condition as to give out the greatest heat of whichthe gas is capable. The tip 0 of the burner forms an enlargedcone-shaped disk above, which is retained in the deflector e by means ofthe standard e, connecting said deflector with the disk 0.

From this construction it will be seen that the mixture of atmosphericair and gas issuing from the top of the burner strikes the under side ofthe deflector and is thrown outward and downward. periphery of thedeflector, from which the flame rises in a tubular form, nearly fillingThe "as ignites at the IOO the lower end of the radiating-pipes abovethem. From this point the heated gases pass upward, as shown by thearrows in Fig. 2, into the chamber D, by which they are returned to theopposite row of radiating-pipes and conducted downward to the chamber13, thus giving an extended course for the passage of the pro 'lucts ofcombustion throughout the pipes and chamber before they can escape tothe flue.

The gas-supply pipe may, if desired, be carried in bearings, which willallow of its partial rotation by means of a handle (I attached thereto,thus bringing the burners into a more convenient position for lighting.This construction, however, and arrangement of the rotatable supply-pipeform no part of this invention, it being fully shown and described inthe application of Jonathan Johnson for a patent for improvements inheating apparatus, filed October (5, 1888, Serial No. 28?,l08.

The modification shown in Fig. 5 consists in a plate f, secured to thebase A and proj ecting inward over the burner to supply the place of thedeflector when said deflector is not used.

-1Iaving thus described our invention, we

claim as new and desire to secure by Letters Patent the following:

1. As an improvement in gas-heaters,1he

combination of the radiating-pipes, the rotatable pipe E, supportedbeneath said radiating-pipes, the burners carried by said rotatablepipe, and the deflectors fixed over the orifices of the burners,substantially as and for the purpose set forth.

2. As an improvement in gas-heaters, the radiating-pipes, in combinationwith the rotatable pipe E, supported beneath the mouths of the saidradiating-pipes, the burners carried by said rotatable pipe, and thesupplypipe I), for carrying air to the base of the burne substantiallyas and for the purpose set forth.

3. As an improvement in a gas-heater, the radiating-pipes, incombination with the rotatable pipe E, supported beneath the mouths ofthe said radiatingnpes, the burners carried by the rotatable pipe, thedeflectors fixed over the orifices of the burners, and the airsupplypipe leading to the base of the burner, for the purpose specified.

In testimony whereof we affix our signa tures in presence of twowitnesses.
